Description

Technical Field

[0001] The utility model relates to the technical field of cement mortar fluidity measurement, in particular to a cement mortar fluidity measurement instrument. Background Art

[0002] The fluidity of cement mortar is a measure of the fluidity of cement mortar. Under a certain amount of water, the fluidity of cement mortar depends on the water demand of cement. The fluidity of cement mortar is expressed by the average diameter of cement mortar spread on the flow table.

[0003] In the prior art, similar to the above-mentioned cement mortar fluidity test mold, mortar is stacked by movably clamped lower truncated cone membranes and upper truncated cone membranes. Although it is convenient to determine the height of the mortar added each time, the truncated cone membrane needs to be removed after the cement mortar is placed. Since the lower truncated cone membrane surrounds the outer periphery of the cement mortar, a slight shaking during the removal process will cause the cement mortar to deform, resulting in test errors. At the same time, in order to prevent the mortar from escaping to the outside of the platform, a fence is usually set on the platform. However, due to the existence of the fence, it is inconvenient to clean the mortar after the test is completed. Therefore, a cement mortar fluidity tester is needed to solve the above problems.

[0005] In view of the deficiencies in the prior art, the utility model provides a cement mortar fluidity measuring instrument, which solves the problem of the cement mortar fluidity testing mold in the prior art being similar to the above-mentioned one. The mortar is stacked by means of a lower truncated cone membrane and an upper truncated cone membrane that are movably connected. Although it is convenient to determine the height of the mortar added each time, the truncated cone membrane needs to be removed after the cement mortar is placed. Since the lower truncated cone membrane surrounds the outer periphery of the cement mortar, a slight shaking during the removal process will cause the cement mortar to deform, resulting in test errors. At the same time, in order to prevent the mortar from escaping to the outside of the platform, a fence is usually set on the platform. However, due to the existence of the fence, it is inconvenient to clean the mortar after the test is completed.
